CARBURETO R.

SPECIFICATION forming part of Letters Patent No. 262,651, dated August'15, 1882,

Application filed December 24, 1881.

To all whom it may concern:

Be it known that I, HENRY 0. DE WI'IT, a citizen of the United States,residing at the city of Chicago, in the State of Illinois, have inventedcertain new and useful Improvements in Carburetors for PortableGas-Machines, of which the following is the specification.

The nature and object of my invention is to provide a 'means whereby thevapor arising from the naphtha or gasoline and the air will bethoroughly intermingled, and in such quantities as will produce asatisfactory illuminating-gas.

Figure 1 is a perspective view of my improveinent with the upper half ofthe case removed, showing the drum with its jacket. Fig. 2 is an endview of same showing one means of adjusting the jactet at end of drum.Fig.3 is an end view of same showing another manner of adjusting jacketat end of drum.

Fig. 4 is a vertical section of carburetor.

Similar letters of reference refer to similar parts in the drawings.

I employ mechanism similar in construction 2 to that shown and describedin my Patent No. 149,163, dated November 8, 1881, for forcing the gasinto and through the pipes.

Around the revolving drum I place a jacket, A, of cloth of thick andcoarse material. This o jacket embraces the entire outer surface of thelrum,and extends overthe ends of drum, and

is gathered around the axis thereof at a short distance from it byastrong thread or cord, as shown at B, Figs. 1 and 3. Instead of ex- 3 5tending the jacket over the ends of the drum and gathering it, as abovedescribed, it can be extended out a short distance over the end andfastened to a head of cloth, separate and apart from thejacket-,as shownat O,Fig. 2. In Fig.4is shown therelativeposition of thejacket, thedrum, and interior of the drum. D, Fig. 4, is the air-tube connectedwith the case E.. As the drum is revolved this jacket throughout itsentire surface is immersed in the fluid 5 used for making the gas, and,as successive (No model.)

parts arise from the fluid in consequence of its fibrous nature, carrieswith it more or less of the fluid, or, in other terms, the jacket at alltimes is more or less saturated with the fluid.

Airis admitted into the carburetor through the air-tube D, and passesalong between the casingandjacketAand through the head 0 into theinterior of the drum and through the disseminators I, which are the samein construction and operation as those I employ in my Patent No.149,163, and dated November 8, 1881, and are made by stretching a pieceof coarse fabric on a suitable wire frame, and placed, one in eachcompartment of the drum, obliquely to the axis thereof, the wider endbeing placed at the periphery of one end of drum and the narrow end atits axis.

I am aware that the drum or pump of a carbureting-machine has beencovered with textile fabric. In my improvement 1 do more than this. Iextend the jacket A over each end of the drum, and at the open end ofthe drum it forms a diaphragm.

I claim- 1.. In a carbureting-rnachine, the combination of a drum havinga closed metallic end and an open end,'and ajacket of textile ma terialcovering the cylindrical portion and solid end, and a head-piece ordiaphragm stretched across the open end of the drum, all constructed andarranged substantially as and for the purpose specified.

2. In a carburetingmachine, the combination of the metallic drum havinga closed and open end, and a jacket of textile material covering thecylindrical portion and closed end of said drum, and stretched acrossthe open end of said drum, with the disseminater I and Y air-inlet andgas-outlet pipes, as described.

HENRY 0. DE WITI.
